Address:

Sikar, Rajasthan

Sir, i jc 664549m ex sub maj (Hony) ram kumar singh mahla, old ppo no s/18765/2016 (Army) retired on 30 june 2016. I have not received corrigendum ppo as per 7th cpc in spite of 24 months have elapsed. One of my colleagues from arty record who have retired in august 2017 have not only received new ppo but received all arrears in last month ie. Jun 2018. What is problem?
7th central pay commission is effective from 01 jan 2016 but still we are not received our entitlements. Request expedite the case and do let me know the present position. Thanking you.
